Solution Overview
Problem
Current technologies for stimulating skin lack effective methods to induce cyclical mechanical strain at specific frequencies, which are essential for promoting anti-aging effects by upregulating protein production in the skin.
Innovation Solution
A system comprising a motor-driven end effector with multiple contact points, positioned at a target distance based on the inverse of the stimulation frequency, applies cyclical mechanical strain to the skin, inducing a stimulus within the frequency range of 65 Hz to 120 Hz to enhance skin health and anti-aging effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a motor-driven end effector with multiple contact points is used to apply cyclical mechanical strain to the skin, then anti-aging effects and protein production are upregulated, but the device complexity increases
Solution Approach 1:
The end effector is divided into multiple contact points (at least two) that are spatially separated and independently positioned relative to the skin surface. Each contact point applies mechanical strain to different locations, creating a segmented approach to delivering cyclical strain that upregulates protein production more effectively than a single contact point while maintaining manageable device complexity through modular design
Solution Approach 2:
The motor drives the end effector to apply cyclical mechanical strain at specific frequencies (e.g., 1-10 Hz) to the skin. This periodic action creates oscillating forces that stimulate cellular mechanisms for protein synthesis and epidermal cohesion. The controlled frequency and amplitude of the cyclical motion enable reliable anti-aging effects without requiring overly complex control systems
Solution Approach 3:
The device utilizes mechanical vibration through the motor-driven oscillation of the end effector contact points against the skin. The vibrational motion at controlled frequencies delivers cyclical strain that penetrates the skin tissue to stimulate fibroblast activity and collagen production. This mechanical vibration approach achieves reliable biological effects using standard motor technology rather than complex actuation systems
2Reliability
If the contact points are positioned at a target distance based on the inverse of the stimulation frequency, then the cyclical mechanical strain is optimized for protein production, but the manufacturing precision requirements increase
Solution Approach 1:
The design specifies that contact points be positioned at a target distance from each other, where this distance is determined by the inverse of the desired stimulation frequency (d = 1/f). For example, at 5 Hz stimulation, the contact points are positioned approximately 0.2 meters apart. This parameter-based design allows manufacturers to achieve frequency accuracy through controlled variable adjustment rather than requiring extreme precision in contact point placement, as the system can be calibrated to compensate for minor positioning variations
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively upregulates protein production, particularly integrin, leading to improved epidermal cohesion and anti-aging effects by applying cyclical mechanical strain at specific frequencies, thereby enhancing skin health and appearance.
Implementation Method 1
The motor is configured to move the end effector such that, when the motor is operating, the system has an oscillating frequency based on the target stimulation frequency
Implementation Method 2
When the motor is operating and a force is applied to the system to bias the end effector toward the portion of skin, the end effector produces a cyclical stimulus within the portion of skin at about the target stimulation frequency

AI summary
An end effector is capable of being used to stimulate a portion of skin at a stimulation frequency. The end effector is couplable to a motor and has a singular contact point or a plurality of contact points at which the end effector is configured to contact the portion of skin. The singular contact point is located at an offset from a center of the end effector or the plurality of contact points are located at a target distance from each other that is based on an inverse of the stimulation frequency. When the base portion is coupled to the motor and the motor is operating, the end effector has an oscillating frequency based on the stimulation frequency. When a force is applied to bias the end effector toward the portion of skin, a cyclical stimulus is produced within the portion of skin at about the stimulation frequency.
